[0030] The working principle of the above embodiment is:

[0031] (1) When in use, the disinfection barrel 4 is inserted into the mounting hole 3, and the tooth plates 501 on both sides thereof are respectively meshed with the two gears 503, and then the motor 504 is started, the motor 504 drives the transmission rod 505 to rotate, the transmission rod 505 drives the two driving wheels 507 to rotate, the two driving wheels 507 drive the two transmission wheels 508 to rotate through two belts 509, the transmission wheels 508 drive the two worms 506 to rotate synchronously in the same direction, further the two worms 506 drive the two worm wheels 510 to rotate synchronously in opposite directions, the worm wheels 510 drive the two rotating rods 502 to rotate synchronously in opposite directions, the rotating rods 502 drive the two gears 503 to rotate synchronously in opposite directions, and then drive the tooth plate 501 to move up and down, driving the disinfection barrel 4 to move up and down for lifting.

[0032] (2) When steam sterilization is required, the steam generator 601 is started to generate steam, and then the fan 602 is started to transport the steam through the air supply pipe 603 to the steam channel 605 inside the steam bin 604, and further sprayed onto the sterilization barrel 4 through multiple air outlets 606 on the inner wall of the steam bin 604 to perform high-temperature sterilization on the micro medical waste inside. When the high-temperature steam is sprayed from the air outlet 606, due to the inclined setting of the air outlet 606, the sprayed steam will generate a reaction force to push the steam bin 604 to rotate, thereby improving the contact between the steam and the sterilization barrel 4. When the sterilization is completed, the valve on the three-way connecting pipe at the air inlet end of the fan 602 is controlled to allow the fan 602 to draw natural wind and blow it on the sterilization barrel 4 to cool it down.
